Update and Quetion

Update: I started my period last Tuesday, 24 April 2012. It was a regular period: lining, blood, 7 days, cramps, bloating, mood swings, and the whole sha-bang. My question is this: Should I go back on the birthcontrol or should I wait to see if it goes back to normal and/or when I ovulate? Also, if I wait, should I buy those ovulation testers to see if/when I ovulate?? If my periods do not go back to normal, should I go see a doctor to test whether I'm ovulating at the right time and if I have a medical condition? If my periods do not go back to normal, should I test for ovulation anyway?? Sorry Ladies for all the questioning and updates, but I'm trying. I really am trying. At this point, I've been trying for close to a year (June would make a year) to get pregnant and, apparently, there's been no luck thus far. According to some medical definitions that I've looked up, I COULD BE infertile. Which worries me to no end. I'm NOT saying that I am infertile, but I am saying that there's a great possibility.
